Effect of Moving Endwall on Hub Leakage Flow of Cantilevered Stator in a Linear Compressor Cascade
文献摘要:
The cantilevered stator has the advantages of reducing mass and axial length of highly loaded com-pressor.The details of the hub leakage flow resulting from the clearance between the high-speed moving hub and the cantilevered stator hub are unclear.In this paper,the effect of a moving endwall on the hub leakage flow of a cantilevered stator in a linear compressor cascade was studied.After the simulation method was verified with the experimental results,the time-averaged results of unsteady Reynolds averaged Navier-Stokes(URANS)were selected to study a case with a hub clearance of 2 mm.The results show that the effect of the moving endwall of the cantilevered cascade on the general characteristics with below 30%span increases the leakage mass flow rate and reduces the static pressure coefficient at three conditions of 0°,6°,and-7° incidences,and the change is most significant at-7° incidence.The effect of the moving endwall on the total pressure loss coefficient varies with different operating conditions,which decreases by 15.94%at 0° incidence,and increases by 4.77%and 18.51%at 6° incidence and-7° incidence,respectively.The influence of the moving endwall is below 14%span at-7° incidence,below 23%span at 0° incidence,and below 30%span at 6° incidence.These effects correspond to the static pressure coefficient and the difference of static pressure coefficient representing the blade loading.In designing the cantilevered stator and matching between the stages of a multistage compressor,the quantitative research results of this paper have certain guiding significance.
